Bookmark or Share- Natural psychedelics in the treatment of depression; a review focusing ...Muscimol is a potent agonist of all gamma-aminobutyric acid type A (GABA-A) receptor subtypes and has a mild sedating effect. Ibotenic acid acts similar to excitatory glutamate neurotransmitter, having a distinctive neurotoxic effect [19]. The psychoactive dose of muscimol and ibotenic acid is estimated to be at 6 mg and 30–60 mg, respectively.
- Muscimol - an overview | ScienceDirect TopicsOnce absorbed, muscimol and ibotenic acid appear to cross the blood–brain barrier by an active transport system. Ibotenic acid decarboxylates to form muscimol in the stomach, liver, and brain (Nielsen et al., 1985). Muscimol and ibotenic acid can be detected in urine within 1 h of exposure (Ott et al., 1975).

- Classics in Chemical Neuroscience: Muscimol - ScienceDirectMuscimol (3) is a psychoactive isoxazole present in various Amanita mushrooms, along with ibotenic acid and muscarine. It is structurally related to GABA and acts as a GABA A agonist with great affinity. Muscimol use dates back to Siberian shamanic cultures as an entheogen, where it was ingested orally to exert psychoactive effects.
